RANDGOLD TO MOVE QUICKLY ON ADVANCING MOTO PROJECT

London, 15 October 2009 — Randgold Resources plans to move swiftly towards a bankable feasibility study on the Moto gold project following the completion today of its business combination transaction with Moto Goldmines Limited, chief executive Mark Bristow said.

Moto shareholders earlier voted in favour of the deal in terms of which they will exchange their Moto shares for Randgold shares or cash. Simultaneously, AngloGold Ashanti has acquired a 50% indirect interest in Moto for cash and Randgold and AngloGold will be jointly responsible for developing the Moto project, which will be operated by Randgold. Moto owns a 70% stake in the Moto Gold project. The government of the Democratic Republic of Congo, through OKIMO, holds the remaining 30% interest in the project, which is Moto’s principal asset.

The Moto gold project is one of the largest undeveloped gold deposits in Africa. A feasibility study completed by Moto in March 2009 envisages an open pit and underground mining operation with probable mineral reserves of 5.5 million ounces which is planned to produce some 2.4 million ounces of gold in its first five years.

“The Moto deal essentially represents the acquisition of an opportunity to convert a very big if technically challenging gold deposit into a profitable mine,” Bristow said. “This is in line with our growth strategy of creating value by developing discoveries rather than paying a premium for established operations. It marks our expansion into a new and exciting gold belt, while retaining our African focus.”

Bristow noted that the Randgold capital projects team which would be responsible for Moto was the same one which had successfully developed the Morila and Loulo mines in Mali and was currently building the Tongon mine in Côte d’Ivoire. Randgold’s proven ability to find, finance, develop and operate mines in Africa would be enhanced at Moto by AngloGold’s own considerable resources and expertise, he said. The two companies already have a joint venture at Morila.
